RT and LimeSurvey are probably not good fits for FOSS4LIB. To try to keep the scope manageable (and not replicate other directories like Fresh Meat), packages in FOSS4LIB meet this definition: if it is open source, is used in libraries, and has components/plugins that are specific to libraries, then it can be included as a package in the FOSS4LIB registry. Comments about whether this scoping make sense are also welcome, but that is where we are now.

Where on the site can I find a definition/description for the different categories of listed softwares, please?
For example how do you describe:
- Content Management System
- Content Management Framework
- Electronic Resources Management
